The International Independent Group of Eminent Persons (IIGEP) has accused the Sri Lankan government of lacking the political will to address human rights. Colombo had invited the group to help investigate certain cases of human rights abuses, including the massacre of 17 aid workers in 2006. But the group quit last month, accusing the government of hindering its enquiries. On Tuesday, the IIGEP held a press conference in Colombo -- the first since it stepped down.
